Hey guys I need help!

What can anyone suggest for dealing with the code 11-06 which states that it is a 4th gear malfunction solenoids A,B,hydraulic issues etc. I only notice an occasional lag regarding the 4th gear when i accelerate on to the highway and or when i tend to pass someone if say i am already up to 80 mph. That extra punch/boost seems to be missing? The tranny will eventually move up but tends to lag/get hung up around 4000 rpm's or so. It shifts fine when i am cruising 75-80 plus mph @2300-2600 rpm's. When I do city driving (1-2%) it shifts fine. The dealer told me that this is very rare, if almost unheard of. Has anyone else experience any of these issues? And again what might the most if not best that i can do regarding this issue? I don't beat the Sh%t out of it, and I have a excellent maintenance regimen, also my fluid is not over heating and or burning up. And I never had any over heating issues, ever. My knock sensor and my EGR valve solenoid codes have also come up, could they be part of my possible tranny hydraulic problems? If I have to get another tranny i will do so, but can i avoid from doing do if this situation can be fixed? Again all of my gears work, its just the off/on 4th gear lag. Is my tranny dying slowly? And are there any solenoids and or other electric parts on the tranny exterior, I am very mechanically inclined what can i do? Please all experiences, suggestions are welcomed 96SE auto 167,300 miles (since new) My apologizes for such a long thesis.

This has some troubleshooting you can do.
Also, Chilton manual lists the TC clutch solenoid valve as the item to check on pg 4-27.


DTC 1106

Diagnostic Trouble Code 1106 means "Automatic Transmission 4th gear malfunction."
This malfunction is detected when the automatic transmission does not shift into fourth gear or the torque converter clutch does not lock up as instructed by the Transmission Control Unit. The factory service manual lists these possible
causes...
- Shift solenoid A
- Shift solenoid B
- Overrun clutch solenoid valve
- Line pressure solenoid valve
- Each clutch
- Hydraulic control circuit
- Torque converter clutch solenoid valve

You can do some troubleshooting without opening the automatic transmission. Find the harnesses which
emanate from the transaxle. One of them terminates in a brown plastic connector with eight pins. This is
connector F42, located (approximately) above the transaxle case and below the black plastic engine air intake
ductwork. With the engine off, disconnect F42. You want to measure the transmission side of F42. Hold the
connector such that the plastic latch is at the top. You should now see two rows of four terminals. These are
numbered (top row, left to right) 1 - 4, and (bottom row, left to right) 5 - 8. Make resistance measurements
between a clean ground and the following terminals:
#1, Shift solenoid B, 20 - 40 ohms.
#2, Shift solenoid A, 20 - 40 ohms.
#3, Overrun clutch solenoid valve, 20 - 40 ohms.
#4, Line pressure solenoid valve, 2.5 - 5 ohms.
#5, Torque converter clutch solenoid valve, 10 - 20 ohms.

There is also a "bench test" procedure for testing these solenoids with a 12 volt supply such as a car battery.
However, this requires removal of the shift solenoid valve assembly. I don't know if you want to get involved
with that.

 

thanks, i already have the chilton manual, in fact i just found it after weeks of digging through my huge book collection Funny thing though the tranny shifted really well today. The dealer further stated that it might be the speed sensor,TCM,drop resistor,etc. I will check and test my connections and go from there. Thanks again!

Best Regards

 

my auto did the same thing as ur describing.shifted kinda funny at high speeds and lagged when i would punch it but after about a week or so the tranny DIED.........AHHHH
good thing im under warranty so it only costed $25 to fix.

 

how many miles did you have on your tranny prior to its death
